GBI7254SMBR from GOSEMICON, in a SOIC-8L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	ENA	input	Channel A Enable Input. Biased low disables Channel A output regardless of INA state. Biased high or floating enables Channel A output. Logic threshold ~2.1V typ, absolute max range -5V to 26V.
2	INA	input	Channel A logic input. Drives OUTA via non-overlap driver. TTL/CMOS compatible with ~1.1V hysteresis. Accepts negative voltage down to -5V for improved noise immunity.
3	GND	power_in	Power ground return for the device. Common return for both driver channels.
4	INB	input	Channel B logic input. Drives OUTB via non-overlap driver. TTL/CMOS compatible with ~1.1V hysteresis. Accepts negative voltage down to -5V for improved noise immunity.
5	OUTB	output	Channel B gate driver output. 5A peak source/sink current with ~10Ω pull-up and ~0.6Ω pull-down resistance. Rise/fall times 8ns/6ns typical into 1nF load. Drives MOSFET/IGBT/GaN gates from GND to VDD.
6	VDD	power_in	System power supply input. Operating range 4.5V to 24V. UVLO threshold ~4.2V rising with ~300mV hysteresis. Requires local bypass capacitor for peak gate-drive current.
7	OUTA	output	Channel A gate driver output. 5A peak source/sink current with ~10Ω pull-up and ~0.6Ω pull-down resistance. Rise/fall times 8ns/6ns typical into 1nF load. Drives MOSFET/IGBT/GaN gates from GND to VDD.
8	ENB	input	Channel B Enable Input. Biased low disables Channel B output regardless of INB state. Biased high or floating enables Channel B output. Logic threshold ~2.1V typ, absolute max range -5V to 26V.
